Those things have one big APU (with weak CPU cores), some VRM and memory, GDDR5 + useless DDR3. I'd discount the APU as it'd need someone to make OS support for with the blessing of Sony/Microsoft. That leaves the chips of GDDR5, which can be used by low end GPUs - I don't think they'd ever recoup and investment and likely cheap manual labor of preheat + hot air is the easier option. No idea if anyone would get a license from AMD or NVidia for such GPU.

Edit: the capacitors would have the best value but well... I cant see anyone relying on old caps for anything but repair.
